I’m guessing we must be around the same age. I’m equally pervy and obsessed with Pam. Fortunately I DID record it. It goes without saying though, that the tape is pretty old. The sound’s diabolical and slightly out of sync, and I think it was filmed in a sort of soft-focus, to simulate an underwater setting.
It looks like her ‘shells’ were loosely attached to a sort of semi-transparent body stocking. I remember also, back then, thinking I saw a nipple at one point.

If her nips can show through a sweater, ( as in the Mork and Mindy episode below) I don’t see why they shouldn’t be visible through a thin flesh-coloured body stocking.
The jury’s out…!

My copy is low-res as well. You can vaguely make out (VERY briefly) her right breast in profile as she takes her top down in this dark bedroom scene, but I have my doubts as to whether it’s her natural boob… Seems a bit large for her..!
